ERROR AND CALCULATION RANGES
1. Errors
An error will occur if an operation exceeds the cal-
culation range on page 221, or if a mathematically
illegal operation is attempted. When an error occurs
the calculation cannot be continued unless the error
is first cleared by pressing ,
e Thenumber following the indicator "Er" is an error
code. Since this code indicates the type of error,
carefully check the code number and its mean-
